EMIL MOELLMANN, OF CINCINNATI, OHIO, ASSIGNOR OF ONF-HALF TO JOHN G. MUFDOOK, OF SAME PLACE.

WATER-CLOSET VALVE.

SPECIFICATION forming part of Letters Patent No. 266,870, dated October 31, 1882.

Application filed September 4, 1882.

To all whom 'it may concern:

Be it known that I, EMIL MOELLMANN, acitizen ot' the United States, residing at Cincinnati, in the county ot' Hamilton and State ot' Ohio, have invented certain new and useful Improvements in Water Closet Valves, of

which the following is a specification.

My invention consists in combining an accumulating-vessel with an automatically-actio ing water-closet valve, the connection between said vessel and the valve-chamber being such that when a wasteway in the former is opened the automatic valve will open and allow water to tiow through the dashing-pipe intothe basin, while the closure ot' said waste 1ay will cause a gradual seating of the automatic valve, and thereby stop said tlushing operation, as hereinafter more fully described, and pointed out in the claims.

In the annexed drawings, Figure l is a sectionized elevation of a water-closet provided with my valve-regulatin g appliances, the wasteway ot' the. accnmulating-vessel being closed. Fig'. 2 is an enlarged axial section of said vessel and the valve-chamber, the wasteway being open, and the automatic valve shown in 'the act ot receding from its seat. Fig. 3 represents one ot' a number ot' modifications ot' my invention.

A represents any approved t'orm ot' watercloset basin or bowl, said basin being connected to the trunk B in the customary maxiner. Secured to the lower end ot' this trunk is a soil-pipe, O, and seat D, the latter serving as a bearing i'or a suitable discharge-valve, E, operated by a litter-rod, e, traversing a tube,

F, to which an overflow-pipe maybe connected,

as indicated by the dotted lines j'. 'This tube is screwed into the cap b ot' trunk B, and said 4o cap b has fastened 011 it an accumulating-vessel, Gr, ot'any suitable shape and size, although it is preferably cylindrical. Vessel G may have a base-flange, g, capable ot' being bolted to this cap; but I prefer screwing the lower end ot' said vessel into a thimble, H, which thimble engages with the cap, as seen in Fig. 2. I is a detachable head ot' vessel Gr, within which latter is located a guide-tube, J, prefer'- ably screwed into the thimble H, and having (No model.)

a seat, K, i'or valve or plug L,`which plug, 5o when closed, prevents water escaping from wasteway j at the lower end ot' said tube. 1" are inlet-ports ofthe tube J. Plug L is adapted to play tx'eely within its guiding-tube, and has a depending stem, Z, projecting down into the trunk B, as seen in Fig. 1. The upper portion of vessel G has a sidepipe, N, comnninicati-ng with a chamber, O, provided at top with a cap, o, and at bottom with an inlet-pipe, P, terminating with a raised seat, p. This chamberis 63 traversed with a piston, It, provided with a Cuppedleather packing, 1', and a disk-valve, s, the latter being' adapted to closeon the raised seat p. Furthermore, this piston should have au upwardly-projecting stein ot' such a length 65 as to prevent said piston ascending so t'ar within chamber O as to close the pipe N; or the same result may be accomplished by a stump depending from the cap 0 ot' said chamber. T is the outlet or discharge pipe ot' valve- 7o chamber O, said pipe being arranged so as to wash the contents out ot' basin A. Connecting the lower portion of vessel G with supplypipe P is another' side pipe, U, having a1 cock or valve, V, that can be opened or closed to a greater or less extent, as occasion may require. The operation ot' my valve attachments is as follows: In case the closet should be situated where there is a considerable head ot' water, valve V must be almost entirely closed, so as 8o to allow but a very limited ilow to take place through the pipe Uinto the accumulating-vessel G, while a reduced pressure would necessitate aI corresponding opening ot' said controlling-valve. This valve having been properly adjusted, it is evident water will dow through pipe U into vessel Gr, and thence through pipe N into chamber O, thereby tilling said vessel andthe space above the piston-valve It S, Consequently said valve is maintained securely ou 9o its seatp, while at the sume time plug L rests on the bearing K, by which arrangement the pressure ot' water in the apparatus prevents any escape either at the wastewayj or wash-pipe T; but as soon as val ve E is raised, so as to empty the contents of basin A down the soil-pipe O, said valve comes in contact with the end ot' stem Zand elevates plug L within the tube J,

Q 4 gaeste ffl-'J as seen in Fig. 2. This elevation of plug L causes the contents ot' vessel G to drain out through the wasteway j, and the pressure being now removed from valve R S the latter at once ascends within chamber O, thus uncovering the seat p and allowing water to escape through pipe T, and thereby wash out the basin A. When discharge-valveEdescendstoits normal or closed position the plug L is instantly seated on its bearing K, thereby preventing further escape through the wasteway j. As a result of this closure. of plug L, water gradually flows through the contracted passage of valve V, and in the course of several minutes vessel G is illed, and sufcient pressure is again brought to bear on valve R S to force the latter down on its seat p, and thus cut off the supply through wash-pipe T.

From this description it will be seen that the flow through the wash-pipe must continueuntil vessel G is completely filled and sufficient water has accumulated in the chamber 0 to close the valve It S, which continuous flow insures a thorough cleansing of the bowl A. It is also evident that the 'time required for tilling the vessel G will depend entirely on the area of opening afforded by the controllingvalve V, which may be set so as to cause an almost instantaneous descent of the pistonvalve R S, or so as to allow several minutes to elapse before this descent takes place.

The above is a description of the preferred construction of my water-closet valve; but the details thereof may be varied to suit circumstances-as, for example, a diaphragm or other form of valve may be substituted for the device R r S; or the wastewayj may be opened independently of the discharge-valve E, one form of such a modification being seen in Fig. 3, where vessel G is shown provided with a valve, WV, to close the wasteway j, said valve being operated by a rod, X, depressed by the seat Y. Z is part of the spring that elevates said seat. In another modification the valveehamber O may be mounted directly on the vessel G, with the inlet P and outlet T at the upper end of said chamber O, in which event the valve R S or its equivalent would closel with an upward instead of a downward movement. 1n this construction the external pipes, N U, could be omitted and their office be performed by a suitable channel, either cast or bored in the side of valve-chamber O, a con trolling-valve similar to the one V being applied to said channel. Finally, a special ves sel, G, may be dispensed with and the pipe N be carried upa suitable distance, and then returned and connected to pipe U; or the same result may be accomplished by interposing a communicating coil between these conduits N U; but in either case some provision must be made for draining these pipe-reservoirs, so as to control the movements of valve R S, for the purpose herein described.

I claim as my invention- 1. The chamber O, having an outlet, T, and an inlet, I), which latter is opened and closed by an automatic valve, as R S, said chamberY and inlet communicating respectively by the pipes N and U V with the vessel G, whose wasteway j is opened by some of the operating appliances ot' the water-closet, substantially as herein described, and for the purpose set forth.

2. In combination with the vessel G, communicating by pipes N U V with the cylinder O P T, traversed by the automatically-acting valve R 1' S, in the manner described, the Wastewayj, closed with the plug L, which latter is operated by the discharge-valve E of the closet, as herein described.

3. The vessel G, communicating with the valve-chamber O in the manner described, said vessel being screwed into the thimble H, with which latter is engaged the pert'oratedguidetube J j, provided with the wasteway j, for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

EMIL MOELLMANN.
